24 participants in 2 patient groups

High-flow nasal oxygen during sleep endoscopy

Experimental group

Description:

High-flow nasal oxygen will be applied to the patients through nasal openings using Optiflow system during sleep endoscopy. Pulse oximetry will be monitored continuously. Otorhinolaryngologist will observe the degree of upper airway obstruction during sleep endoscopy.

Treatment:

Procedure: High-flow nasal oxygen

Low-flow nasal oxygen during sleep endoscopy

Active Comparator group

Description:

Low-flow nasal oxygen will be applied to the patients through nasal openings using conventional nasal cannula during sleep endoscopy. Pulse oximetry will be monitored continuously. Otorhinolaryngologist will observe the degree of upper airway obstruction during sleep endoscopy.

Treatment:

Procedure: Low-flow nasal oxygen
